It should be noted that the coupling reactions of the aryl chlo-
rides (entries 36–38), also took place under similar copper-free
conditions, though the reactivity was much lower than their iodo
and bromo counterparts (entries 1, 2, 6, 19, 20, and 24).
Unsurprisingly, p-nitroiodobenzene and p-nitrobromobenzene
were found to be the most reactive amongst the aryl halides stud-
ied (entries 2, 9, 15, 20, 26, and 31). In all reactions, only 1 mol% of
PS-ppdot-Pd(II) based on the aryl halides was used, the turnover
frequency (TOF) was larger than that in the corresponding cou-
pling reaction catalyzed by other polystyrene-supported catalysts
reported [82,83].

is to enable recycling of the catalyst for use in subsequent reac-
tions. For the recycle experiment, we used phenylacetylene and
iodobenzene as the representative reactants in the presence of
mol% PS-ppdot-Pd(II) to study the recyclability of this heteroge-
neous catalyst. After a reaction time of 3.0 h at room temperature,
the mixture from the first-run reaction was centrifuged, and the

After drying, the recovered PS-ppdot-Pd(0) was then reused in the
same reaction under identical conditions. We found that the prod-
uct yield decreased slightly from 97 to 87% over four recycling runs
Table 3).
In order to determine the absolute amount of the palladium
species dissolved in solution caused by leaching, the crude reaction
mixtures were evaporated to dryness and analyzed using ICP-AE.
It was shown that less than 2% of the total amount of the original
palladium species was lost into solution during the course of a reac-
tion. This almost negligible leaching level, which is at the limit of
detection of the ICP, accounts for the recoverability and reusability
of the palladium resin catalyst.

In conclusion, we have developed a clean and safe proto-
col for the Sonogashira coupling of aryl iodides and bromides
with terminal acetylenes using the PS-ppdot-Pd(II) catalyst to
give various biarylacetylene derivatives. The reactions can be
carried out under copper- and solvent-free conditions in an air
atmosphere. The catalyst used is easily separated, and can be
reused for several times without a noticeable change in activ-
ity. Further investigations for more favorable strategies and
conditions for recycling PS-ppdot-Pd(II) as well as synthetic appli-
